I can tell you that when it comes to intercoolers, size is a factor but it does not define performance by itself. Someone needs to run it back-to-back or at the very least look inside to see what kind of fin design is used on the core to figure out more about it. I personally do not know anyone that has purchased one or run one from the link you posted so unfortunately I cannot help you in that aspect.

i bought my ski from cycle springs, but had no idea they were making their own ebay cores. It looks a little beefier than the stock unit for sure. They are a great company to work with as well, i would give it a shot if i didnt have a cooler already.

A friend of mine just bought the $120 ebay intercooler for his 2006 RXP. He works at a fab shop so he fabbed up everything he needed to stuff it into his hull. He just finished it yesterday so it hasn't been on the water yet. Will let you know what the results are.

I feel reasonably sure this is the one he bought but don't hold me to it.

I would buy a CX before I would buy that other Cycle Springs. We fabricate aluminum and stainless all the time for custom turbo / supercharger kits. If my fabricator welded like that, I would fire him. I also would have no confidence in a pressure test situation on it.

I use a lot of the CX Racing stuff on high end builds here at the shop, and I'm buying a Fizzle 1000...
